What are Django forms and how do I use them?

Django forms are a way to handle user input in web applications. They provide a way to create, validate, and process forms easily.

Can you show me an example of a simple form in Django?

Sure! Here's a basic example:

from django import forms

class ContactForm(forms.Form):
    name = forms.CharField(max_length=100)
    email = forms.EmailField()
    message = forms.CharField(widget=forms.Textarea)

This creates a contact form with three fields.

How do I render this form in a template?

You can render the form in a template using the following code:

<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Send</button>
</form>

What about form validation?

Django automatically validates the form fields when you call form.is_valid(). You can access errors using form.errors.
